FAQ
What sites does VinnerVi support?›
We support YouTube, Bilibili, X, TikTok, Dailymotion, and Niconico. Due to different technical reasons (DRM, non-standard players, etc.) we can't guarantee every video site will work — but feel free to try others! VinnerVi works on any page with a standard video player.
Subtitle vs Audio mode?›
Subtitle mode translates existing captions — faster, cheaper (1 credit/min vs 3 for audio), and more accurate. We've tested it on YouTube and Bilibili since they provide subtitle content. Feel free to try it on other sites with subtitles too! Audio mode transcribes speech first, then translates — use it when no subtitles exist.
How long does translation take?›
Subtitle mode is near-instant. Audio mode takes a few minutes depending on video length.
Where are subtitles stored?›
Locally in your browser. They load automatically on every visit. Only cleared if you clear browser data.
Do I need to keep the popup open?›
No. We'll notify you when it's done. Just reopen VinnerVi on the video page within 3 days to collect your subtitles.
When should I refresh the page?›
Refresh if: (1) you want to start a new translation but VinnerVi can't detect the video, (2) your translation is done but subtitles aren't showing, or (3) you updated the extension. No need to refresh if you just opened the page.
Why are some parts translated less accurately?›
VinnerVi uses state-of-the-art AI language models that produce high-quality translations in most cases. Occasionally, some segments may contain awkward phrasing, minor inaccuracies, or hallucinated words — this is an inherent trait of current AI technology, not a bug. Quality can vary with heavy accents, overlapping speakers, or niche terminology. We continuously improve our pipeline to minimize these cases.
Use this if the popup feels stuck, shows stale job status, or behaves unexpectedly. This removes all cached subtitles, job tracking data, and preferences from your browser. Your account, credits, and server-side data are not affected.
